How Can You Test That Air Flows To All Trailers? [Solved]
Check That Air Flows to All Trailers. Use the trailer handbrake to provide air to the service line. Go to the rear of the rig. Open the emergency line shut-off valve at the rear of the last trailer. You should hear air escaping, showing the entire system is charged.
